NOZZLE FOR HUMIDIFIERS OR THE LIKE.

SPECIFICATION forming part of Letters Patent No. 724,685, dated April 7, 1903.

Application filed July 2, 1901. Serial No. 66,902. (No model.)

To aZZ whom it may concern.-

Be it known that I, QUIMBY N. EVANS, a citizen of the United States, residing in the borough of Brooklyn, county of Kings, city and State of New-York, have invented certain new and useful Improvements in Nozzles for Humidifiers or the Like, of which the following is a specification. 1

My invention provides certain improvements in nozzles for humidifiers and similar apparatus whereby when the nozzles become clogged they may be very easily and surely cleaned out.

Though 'my improvements are especially adapted to use with nozzles which are themselves in comparatively inaccessible places,

. with nozzles of the improved type designed by me. Fig. 2 is a side elevation, on a larger scale, showing the application of myimproved nozzle to a spraying device alone. Figs. 3 and 4 are diametric sections'of my improved nozzle in the two positions which it occupies in use. Fig. 5 represents in side elevation and in plan the movable member of such a nozzle. Fig. 6 is an elevation of the cleaningtool. Fig. 7 is a side elevation of the complete nozzle.

In my improved air-moistening apparatus, as shown, I use the saine general arrangement as described in my application for patent, Serial No. 56,393, filed April 18, 1901, adding thereto, however, a separate sprayingdevice which subdivides the water into minute particles and distributes them into the current of air, preferably in advance of the passage of air through the fan and preferably also above the water-wheel. By the use of my improved self-cleaning nozzle in connection with such an apparatus regularity and contin uity of action of the same are secured.

I make no claim in this application to the humidifier thus improved, having filed a divisional application therefor, (Serial No. 77,581, filed October 4, 1901.)- i My improved nozzle is so arranged that by varying the pressure of water-as, for example, by cutting off the supply or materially continuous work without interruption and, delay for cleaning out the nozzles or pipes.

The cleaning out of the nozzle is effected by a cleaning-tool which is connected to the nozzle and arranged to be moved into and out of the orifice. The movement is preferably effected by making the nozzle in two parts movable relatively to each other, and the cleaning-tool is connected to one of said members and moves into and out of the orifice of the other member as the members are moved in opposite directions by the increase or reduction of water-pressure in the pipe.

Preferably the cleaning-tool is adjustable to vary its normal position relatively to the orifice.

This, I,

Referring now to the drawings, A reprecharge is thrown onto the inner wall" of the:

tubular portion A and drops otfthe loweredge of the same inasort-ofrain, through which the current of air is blown. The basin retains a supply of water up to the level of the outlet, as shown, and also gives up moisture to the current of air being blown over it. I have found that the efficiency of the drivingwheel B is so great that the amount of air passing through the apparatus is such as can take up much more moisture than is afforded. Ifind also that the best results can be obtained by retaining the eflicient water-wheel shown and supplying additional moisture from another source, preferably in the form of a finely-divided spray and preferably, also, at a point above the water-wheel and fan in the upper flaring partof the tubular casing, so that it is completely distributed in all parts of the air, which subsequently passes to the fan. Such a sprayer is shown at E and may comprise a deflecting-plate F of any usual or suitable construction, which receives a jet of water and deflects it in a fine spray in all directions, and a nozzle G for directing the jet of water on the deflecting-plate F.

The arrangement of the connections may be considerably varied, and it is understood that the arrangement shown in Fig. 1 is given merely as an example. The supply of water to the nozzle G used for the spraying device and for the driving-wheel D maybe brought from a main H, which has the usual valve J, controlled from below by cords or chains K.

In the preferred construction of the nozzle G, whereby it is specially adapted for use with the apparatus shown in Fig. 1 or with a separate spraying device E, as shown in Fig. 2, a pair of members L M, Figs. 3 and 4, is provided,the former of which is provided with a screw-threaded base, as at O, or otherwise arranged for attachment to a pipe, hose, or the like. The member L may, in fact, as far as the operation of the device is concerned, he considered a part of the pipe, hose, or the like at whose extremity the nozzle is arranged. The member M has the nozzle-orifice P at its outer end and is preferably arranged to telescope within the member L, a flange Q on the latter and a corresponding flange R on the former limiting the outward movement of the member M. Bearing also on the under side of the flange Q is a spring S, which bears at its other end on a flange T of the member M. This spring is arranged to hold the parts in the position of Fig. 3, but can yield and allow the parts to assume the position of Fig. 4 when the pressure of water is turned on to produce the jet.

A cleaning-tool, preferably in the form of a simple pin U, is provided in such a position that when the spring presses the member M into the member L the pin enters the orifice P to push out any dirt therein. The pin U may be conveniently attached by forming its lower end into one or more convolutions V, adapted to fit into the groove between the screw-threads O and to be held in any desired position of adjustment, the position being determined by screwing it into or out of the member L.

The operation of the individual elements of my improved apparatus being clear, I will briefly describe the operation of the apparatus as a whole. The water being turned on, the fan 0 is operated to drive a current of air in the direction of the arrows, which takes up moisture in the manner explained from the discharge of the wheel D and also from the sprayer E and the basin B. The air is thoroughly charged with moisture, which by the force of the fan is distributed over a large area of the room. If either the driving-wheel nozzle or the sprayer-nozzle becomes clogged, thereby reducing either the rotation of the fan 0 or the amount of moisture supplied by the sprayer E to the current of air, it is only necessary to pull the appropriate cord K long enough to out off the pressure from the nozzle or nozzles G. Thereupon the spring S forces the member M into the member L, so as to cause the pin U to become positioned and held in the opening P and clear out the obstruction. The pressure may be again almost instantly turned on at the valve J, and the pressure of water throws the member M out into the position of Fig. 4and spouting through the orifice P assists in entirely clearing away any particles which have been loosened but not detached by the pin U.

It will be understood that my apparatus is capable of considerable modification by those skilled in the art without departing from the spirit of my invention. Therefore, though I have described with great particularity of detail a complete apparatus embodying my invention, it is to be understood that my invention is not limited to the particular arrangements and details described. It is to be understood also that some details of my invention are capable of utilization in other fields and other combinations than herein shown and that such uses are within my invention.

What I claim is 1. In a nozzle, the combination with a cleaning-tool, of a movable member in which is the discharge-orifice and which is arranged to be moved so that said tool may be positioned in or out of said orifice to clean the same or to permit flow therethrough.

2. In a nozzle, the combination with a cleaning-tool, of a movable member in which is the discharge-orifice and which is arranged to be moved so that said tool may be positioned in or out of said orifice, said tool being adj ustable to vary its position relatively to said orifice in the normal position of the parts.

3. In a nozzle, the combination with a pair of tubular members, one telescoping within the other and in one of which is the nozzleorifice, of a cleaning-tool arranged to be positioned in or out of said orifice as one of said members is telescoped within the other.

4. In a nozzle, the combination of a fixed tubular member, a movable tubular member having a discharge-orifice therein, said fixed ICC member being-adapted to admit the water in the rear of said movable member to force the latter forward, and a cleaning-tool adapted to lie in said orifice in the rearward position of said movable member and out of said orifice in the forward position thereof.

5. In a nozzle, the combination with a pair ofrelatively movable tubular members in one of which is the nozzle-orifice, of a cleaningtool arranged to be automatically positioned in or out of said orifice by a movement of one of said members relatively to the other, and means for causing a relative movement of said member in opposite directions as the water-supply is cut off or is passed through said orifice respectively.

6. In a nozzle, the combination with a pair of tubular members, one telescoping within the other and in one of which is the nozzleorifice, of a cleaning-tool arranged to be antomatically positioned in or out of said orifice as one of said members is telescoped on the other, said member being arranged to telescope in one direction under pressure of the water when it is turned on, and a spring arranged to telescope said member in the opposite direction when the Water is turned 05.

. 7. In a nozzle, the combination with a fixed memberL, of a movable member M telescoping therein, a pin U attached to said fixed member, and a spring tending to hold said movable member M in position with said pin entering the orifice of such member, said spring being arranged to yield and permit the pressure of water to telescope said member M outward to withdraw said pin from said spring being arranged to yield and permit the pressure of water to move said member M outward to withdraw said pin from said orifice.

9. The combination of a nozzle-base, a cap having a discharge orifice and slidably mounted to move toward and fromsaid base, means for guiding the cap, and a clearer or cleaner pin connected to the base and adapted to enter said discharge-orifice, substantially as set forth.
